CONSTRUCTION OF ROADS AND THE LIKE Filed Aug. 10, 1928 Patented Dec. 16,1930 Application filed August 10, 1928, Serial No. 298,756, and in GreatBritain August 27, 1927.

The present invention has relation to the construction of roads, floors,and the like, more particularly the construction of roads aving aconcrete or other like foundation wh with their major dimensionvertically, and crests and depths in adjacency or engagement (as shownin Figure may be manufactured from steel, and are conveniently tion,being slotted inwardly from two 0 or other filling constituting asurface co-vering, the present invention having for its object primarilyto provide for a more eflicient installation of the mesh upon thefoundation.

The present invention consists in the combination with a metallic meshcomprised of strips of metal bent to an undulating, waved. assists inholding the zigzag or equivalent formation and aggreto constitute themesh. gated or adapted to be aggregated together The simple plate suchas aforedescribed is and depths are illustrated particularly in theFigure 5. in register for reinforcing a surface covering 4, however, thefor a road, floor, or the like, of a plurality of metal plates of stripsinterposed or adapted to e interposed superficially between the mesh andits supporting foundation, to lend vertical support or give a. largerbearing surface thereto, and prevent its being forced into thefoundation by heavy trafiic. A locking engagement of the plates orstrips with the mesh may be provided for to prevent relative inengagement (as shown). The plate is disposed between the foundation andthe mesh. and is not only prevented from displacement by its engagementwith the mesh respectto the mesh. In the Figure 1 the tongues 12 areaccommodated within the waves and crests, whereas in the Figure 4 theyare without said waves and crests, the

displacement. parts 5 being accommodated therein; Vir- In order thatthis invention may be clearly tually the only difference resides in thefact understood and readily carried into practhat in the Figural theWaves and crests reference may be had to the appended are spaced a shortdistance apart, whereas explanatory sheet of drawings upon which in theFigure 4- they are in contact or sub- Fi 1 is a plan View of a meshincorstantially in contact. In either instance, porating plate SHPPOIUDg01' r lnf e' loose locating pins 0 may be utilised in assomeansconstructed according to the present mesh, and to this end theinvention. 7

In operation, the undulating zigzag or other strips are arranged on thefoundation in to constitute the mesh, the plates or strips beingassembled between the said mesh and the foundation proper or a superlayer thereof. The filling or surface covering is then applied,consolidating the whole, the plates 15 or strips serving the usefulpurpose of increasing the bearing surface of the mesh and preventing itsbeing gradually driven into the foundation by heavy traflic.

I claim:

20 1. In combination with a supporting foundation, a metallic meshcomprising a plurality of bent metal strips loosely disposed in parallelrelation, the crests and depressions of said strips being opposed, and

I metal plates intermediate said strips and said foundation, said metalplates having upturned portions engaging said strips at various pointsfor holding them in fixed relative position.

2. In combination with a supporting foundation, a metallic meshcomprising a plurality of bent metal strips, the crests and depressionsof said strips being opposed, metal plates intermediate said strips andsaid foundation, said metal plates having upturned portions engagingsaid strips at various points for holding them in fixed relativeposition, and locating members engaging the opposed crests of adjacentstrips.

3. In combination with a supporting foundation, a metallic meshcomprising a plurality of bent metal strips, the crests and depressionsof said strips being opposed, metal plates intermediate said strips andsaid foundation, said metal plates having upturned portions engagingsaid strips at various points for holding them in fixed relativeposition, and locating pins loosely extending through apertures in theopposed crests of adjacent strips.

4. In combination with a supporting foundation, a metallic meshcomprising a plurality of bent metal strips, the crests and depressionsof said strips being opposed, metal plates intermediate said strips andsaid foundation, said metal plates having upturned portions engagingsaid strips at various points for holding them in fixed relativeposition, and locating pins loosely extending through apertures in theopposed'crests of adjacent strips and through apertures in upturnedportions of said metal plates.

In witness whereof I have hereunto set w my hand. 7
